Ajuste de um modelo linear para determinar níveis de sobretensão atmosférica em uma linha de distribuição rural.

Abstract

The knowledge of the transient levels which can strike equipments of Rural Distribution Lines is very important to the development of protection devices. To do so, this work fitted physical parameters relevant to the behavior of atmospheric surge transients of a distribution line through a linear regression, working statistically with transient levels generated by computational simulations. Therefore, it is possible to estimate the threshold transient level that will strike an equipment, improving the effectiveness and ensuring continuous electric energy to the agricultural and industrial process.
